still seems to be a pile of "_append +=" stuff in oe-core

i mentioned this a while back, and it *seems* that there's even more
of this now -- the use of "_append" in conjunction with "+=", which is clearly(?) redundant.

one simply needs to run:

$ grep -r "_append.*+=" *

to see how much of that there is. sure, it doesn't hurt, but it's definitely not good programming practice.

The _append and += are different, so we need either:

var_append = " foo"
or
var_append += "foo"

for example:

var += "foo"
var = "A"

Then var will be "A".

But:
var_append += "foo"
var = "A"

Then var will be "A foo"

Yes, but _append += is not preferred by convention, it just adds confusion. When using _append, make the separator explicit.
